evaluated as substrates for phosphatidylinositol synthase and uptake by intact cells. 1D-3-Amino-, -3-chloro-, and -3-(acetylthio)-3-deoxy-myo-inositols were all synthesized by nucleophilic displacement of the 6-O-(trifluoromethyl)sulfonyl group of 1L-1,2:3,4-di-O-cyclohexylidene-5-O-methyl-6-O-[(trifluoromethyl)-sulfon yl] - chiro-inositol (which was prepared from L-quebrachitol), respectively, by reaction
合成了许多3-取代的1D-肌醇,并将其作为磷脂酰肌醇合酶和被完整细胞摄取的底物进行评估。1D-3-氨基-,-3-氯-和-3-(乙酰硫基)-3-脱氧-肌醇均通过亲核取代1L-1的6-O-(三氟甲基)磺酰基合成,通过与LiN3反应分别形成2:3,4-二-O-环己叉基-5-O-甲基-6-O-[(三氟甲基)-磺酰基]-手性肌醇,然后还原叠氮基官能团,并与LiCl和KSAc结合,得到O保护的化合物。使用BBr3进行O-脱甲基和伴随的乙缩醛水解提供了游离羟基的3-氨基-和3-氯-3-脱氧-1D-肌醇。3-巯基类似物是通过除去乙酰硫基类似物的缩醛基获得的,然后进行过乙酸的乙酰化和纯化,然后进行O-脱甲基和脱乙酰。通过Barton-McCombie脱氧从6-O-(咪唑-1-基硫代羰基)化合物合成3-脱氧衍生物。通过叠氮化物置换,由1L-1-O-甲苯磺酰基-手性肌醇直接合成3-叠氮基衍生物。3-酮类似物是通
